npm i @tria-sdk/web@4.2.27

Create an instance

const solanaWallet = new SolanaWallet({
    baseUrl: "https://dev.tria.so", // or staging for old infra
    walletType: {embedded: true},
    chainName: "SOLANA", // or "SOLANA-DEVNET" // can later add SOLANA-TESTNET too
});

signAndSendTransaction ⛽️

signAndSendTransaction({
    transaction: Transaction,
    gas: Gas
}): Promise<TxnResponse>;

export type TxnResponse = {
    success: boolean;
    data?: {
        txnId: string;
        viewInExplorer: string;
        wait: Function;
    };
    message?: string;
    error?: any;
};

getInstructions

getInstructions({ transaction: Transaction }): TxnInstruction[]

export type TxnInstruction = {
    name?: string;
    programId: string;
    data: string;
};

getEstimatedFee

getEstimatedFee({ transaction: Transaction }): Promise<FeeResponse>

export type FeeResponse = {
    success: boolean;
    fee?: {
        eth: string;
        usd?: string;
    };
    message?: string;
    error?: any;
};

How it works?

• This can be used for any transaction created by the dapp on Solana, and wants to get signed via user's Tria wallet.

• Passing the gas param in the signAndSendTxn function will cut the gas in any token, like USDC, SOL, etc., hence no dependency on SOL native tokens now to make txns

  • This was made possible because of Shyft Txn Relayer, which provides a feePayer to add to any Solana transactions

  • On the basis of the gas estimated, Tria's Solana feePayer will sponsor all that gas in SOL, and the user just has to pay in any token they prefer on Solana.

  • These transactions internally are partially signed by the user's key, as well as by the feePayer for paying the SOL fees.

About WalletController and FeeController

• You can still keep using the WalletController and FeeController for Solana

  • for send, sendNft

  • for getSendFee, getSendNftFee

• Only add the new popup for enabling any Solana transaction via SolanaWallet controller
